No custom skin

When I log into the snapshots, my skin is gone. I am not in offline mode and have internet to both of my browsers. In 1.8, my skin takes an average of 5 seconds to load. (My internet connection is kind of slow.) I have had Minecraft running for about 5 minutes and my skin is still an Alex. I have the full version of Minecraft and I get an internet connection to servers. I have restarted my game multiple times. I don't know if it happens on multiplayer as well.
